摘要
为了评价腐霉利在番茄上的残留状况。指导腐霉利的科学合理使用,本试验选择50%腐霉利可湿性粉剂推荐剂量500.0、750.0g/hm2(有效成分),连续施药2~3次,间隔5d,最后一次施药3、7、10d后采集番茄样品进行残留检测。结果表明,腐霉利在番茄上的残留量为0.075-0.256mg/kg,小于GB2763—2012规定的农药最高残留量(2mg/kg):结合番茄成熟期长,建议腐霉利在番茄上的安全间隔期为10d。
This experiment selected tomato was sprayed 2 to 3 times with 500.0-750.0 g/hm2(effective constituent) of procymindone in interval 5 days. The final residues quantity in tomato is 0.075-0.256 mg/kg when the last spraying procymidone after 3, 7, 10 days. It is less than GB 2763-2012 specified MRL 2 mg/kg value. With the maturation period long, it was suggested that the preharvest interval of procymidone in tomato was 10 days.
